Chapter 9: Troubleshooting
Windows 2000 Driver Problem
There are no actual device drivers required for the HP VT5900-SA Virtual TapeServer SCSI-to-
FC Adapter. When Windows 2000 prompts for a device driver, this situation occurs because the
Active Fabric LUN of the VT5900-SA is enabled. Set the LUN in question to value of 0, in order
to eliminate further Windows driver requests. You can also accept the Windows prompts and dis

able the device in the device manager.
To install (or register) the HP VT5900-SA to a connected host Windows 2000 PC, perform the fol-
lowing steps:
1. Copy the INF file to the Windows 2000 PC which has the FC HBA to be connected to the
VT5900-SA. Typically, the appropriate location to copy the file is as follows:
C:\WINNT\system32\
2. When the HP VT5900-SA “FC Link” LED indicates a good connection, the user can either
reboot the PC or run the Windows 2000 Device Manager “Scan for New Hardware” function.
Either action should result in the HBA issuing a SCSI Inquiry command, to which the
VT5900-SA replies with a ASCII Inquiry string
.
3. Select the Wizard’s “Search for Better Driver” option and specify the folder containing the
VT5900-SA INF file. The Hardware Wizard will scan the specified folder for all INF files and
will select the first INF file it finds with a device entry containing a matching hardware ID
string.
4. Reboot the host PC to complete the process, as prompted by the Hardware Wizard.
Verify SCSI Bus Configuration
Problems with SCSI bus configuration are common. Basic operation of a SCSI bus can be checked
by using the configuration menu to view attached SCSI devices. See “Chapter 7 for more
information. Other conditions to look for include:
• Termination—Problems with termination can cause intermittent or hard failure. A SCSI bus
must be terminated on both ends, and only both ends. Termination issues when both narrow
Note: There must be a controller LUN set up on the HP VT5900-SA so that the Windows 2000
operating system can discover it.
Note: Initially the Windows 2000 Hardware Wizard uses this string to refer to the VT5900-SA.
After this discovery interaction occurs, the Hardware Wizard will prompt the user to install a
device driver.
Note: The Hardware Wizard will copy the selected INF file, renaming it to “OEM<#>.inf,”
where the ‘#’ is some integer, and it will place the copied file into the “C:\WINNT\inf” folder.
The Hardware Wizard will then compile the INF file to a “.PNF” file with the same root
filename and use its VT5900-SA model entry information to install, or register, the newly dis-
covered device.
